AlI and AlII extended transition rates
Listed in IVOA Registry (Virtual Observatory)
MultiConfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction (RCI) calculations were performed for 28 and 78 states in neutral and singly ionized aluminium, respectively.
Description
In AlI the configurations of interest are 3s^2^nl for n=3,4,5 with l=0 to 4, as well as 3s3p^2^ and 3s^2^6l for l=0,1,2. In AlII, in addition to the ground configuration 3s^2^, the studied configurations are 3snl with n=3 to 6 and l=0 to 5, 3p^2^, 3s7s, 3s7p, and 3p3d.
Valence and core-valence electron correlation effects are systematically accounted for through large configuration state function (CSF) expansions. Calculated excitation energies are found to be in excellent agreement with experimental data from the National Institute of Standards and Technology (NIST) database. Lifetimes and transition data for radiative electric dipole (E1) transitions are given and compared with results from previous calculations and available measurements for both AlI and AlII.

The computed lifetimes of AlI are in very good agreement with the measured lifetimes in high-precision laser spectroscopy experiments. The present calculations provide a substantial amount of updated atomic data, including transition data in the infrared region. This is particularly important since the new generation of telescopes are designed for this region.
There is a significant improvement in accuracy, in particular for the more complex system of neutral AlI. The complete tables of transition data are available online.
